      Here's a very concise DCGAN implementation in Keras. Implementing arbitrary deep learning models doesn't get simpler than thathttps://colab.research.google.com/drive/1f3GOVrhwBrtltnwKrafzaKL3fKtIKqgb?usp=sharing …

      Each logical step in the training loop maps to one line of code: exact mapping from mental model to implementation. That training loop supports distributed training and TPU training out of the box, without the user having to work for it.pic.twitter.com/7R2lHKrUdu

      how many epochs does it take to get decent looking images?

      You get face-like images after 15-20 epochs, but results keep improving after that. Images shown in the notebook are from around 30 epochs

      thanks! very impressive that 30 epochs suffice to get reasonable faces. what about super high quality faces? are we talking about say 10x more epochs or much more than that?

      You should use a more advanced model for that, like StyleGAN2.
